Vitiligo and melanoma-associated hypopigmentation (MAH): shared and discriminative features.

Background: It is unclear if differences between melanoma-associated hypopigmentation (MAH) and classical vitiligo exist.

Patients And Methods: Hypopigmented areas and associated lesions (halo nevi, hypopigmented scars) in 15 melanoma patients and 31 patients with classical vitiligo were analyzed by digital photography. The activity of the respective lesions was assessed by the vitiligo disease activity (VIDA) score.
